  • Publication number: 20050197003
    Abstract: A battery contact mechanism energizing a battery in a direction of one electrode of the battery by making pressure contact between a conductive contact member and the other electrode of the battery, includes a torsion coil spring. A rotational force is given to the contact member by the torsion coil spring. The contact member is provided separately from the torsion coil spring.

  • Patent number: 6940415
    Abstract: A reach type forklift truck includes a rotation sensor interposed between a load wheel and a load wheel shaft on which the load wheel is provided. A signal line for transmitting a detected signal of the rotation sensor is inserted in a guide groove formed in the load wheel shaft that extends along an axial direction thereof. The signal line is led out from a reach rail side of the load wheel.

  • Publication number: 20030047389
    Abstract: In a lift truck of a type that, using a brake controller 20, a traveling motor 3 can be braked by an electromagnetic brake 17, the brake controller 20, when it detects the brake operation of a brake operation device, not only actuates the electromagnetic brake 17 but also detects the truck body weight and traveling speed of the lift truck, thereby electrically braking the traveling motor 3 in such a manner that the electric brake force can be increased or decreased in correspondence to whether the thus-detected truck body weight is heavy or light as well as the electric brake force can be increased or decreased in correspondence to whether the thus-detected traveling speed is high or low.

  • Publication number: 20020098487
    Abstract: Nucleic acids for detecting fungi, which have sequences shown in SEQ ID NOs. 3, 57 to 75 are disclosed. The nucleic acids for detecting fungi may be used as probes or primers for gene amplification. In case of using them as primers, detection and identification of fungi belonging to the genus Aspergillus may be attained because the sizes of the amplified nucleic acid fragments vary depending on the species of the fungi belonging to the genus Aspergillus if the primers are appropriately selected.

  • Patent number: 6268562
    Abstract: Sheaths accommodate a high-voltage conductor in their insides, and annular grooves are respectively provided in flanges of the sheaths outwardly of inserting holes for bolts which are disposed in annular form. Annular grooves are provided in an insulating spacer inwardly of the inserting holes for the bolts. O-rings are respectively provided in the annular grooves. An annular groove is also formed in a flange connection face so as to have bolt inserting holes at its bottom. After the flanges have been fixed by using the bolts, nuts and sealing washers, a liquid packing is injected into the flange connection face groove through a liquid packing injection opening which communicates with the groove. Since a sealing element is disposed outwardly of the bolt holes, it is possible to prevent penetration of rainwater or the like into the gaps between connected flanges with airtightness being retained. It is also possible to readily inject the liquid packing into the gaps between the flanges.

  • Patent number: 6067172
    Abstract: A terminal, such as a group 4 (G4) facsimile, coupled to an integrated services digital network has a function for setting up a confirmation call for automatically detecting a change of a different terminal, from a group 3 (G3) facsimile to a G4 facsimile. The G4 facsimile has a memory for memorizing information of a different terminal, such as, for example, a calling number, a short formed calling number under an abbreviated dialing mode, and a corresponding identification whether the different terminal conforms to a G3 or G4 facsimile procedure. The G4 facsimile sets up a confirmation call under the G4 facsimile procedure to confirm whether or not the different terminal has been updated to a G4 facsimile, only at a time of when the different terminal is identified as being conformable to the G3 facsimile procedure by the identification, and, optionally, when an arbitrary time period, which is memorized in the calling G4 facsimile, is exceeded.

  • Patent number: 4462059
    Abstract: A demagnetizing power source for producing an attenuation alternating field to demagnetize a magnetized substance. This power source is provided with a memory circuit for sending actuating signals to a polarity changing-over circuit to change over the polarity of direct current supplied from a rectifying circuit to an exciting coil. In the memory circuit are stored a plurality of preset demagnetizing patterns. The polarity changing-over circuit changes over alternatively the polarity and gradually decreases the change-over cycle according to the selected demagnetizing pattern.

  • Patent number: 4117399
    Abstract: To a light converter including an optical effect element is applied an electric input having an amplitude exceeding the linear region of the characteristic of the light converter. The number of the peaks of the output reaching a maximum amplitude is added to the magnitude of a peak of the output not reaching the maximum amplitude thereby measuring the magnitude of the input. Two or more light converters with differential or cumulative inputs may be used.
